Suprarenal IVC obstruction occurs rarely but has various causes. Because this obstruction proceed chronically and usually has collateral circulation, if there is no IVC or hepatic vein obstruction symptom such as Budd-Chiari syndrome, operation is usually needless. However, although symptom is not combined, if malignancy can not be ruled out and there is no proper and radiologically visible collateral, mass resection with IVC wall and bypass graft should be done. 58 year-old female patient visit the hospital for IVC mass that is occasionally discovered by routine abdominal ultrasonography examination. After abdominal CT scanning and IVC venography, IVC obstructive mass between renal vein and hepatic vein was found. Patient didn't show any abnormality in hematological examination such as coagulation and platelet counts. There was no IVC obstruction symptom such as lower limb swelling. Inferior hepatic vein was abnormally dilated and this was regarded as collateral vessel for IVC obstruction. Radiologically, primary leiomyosarcoma was not ruled out and so operation was decided. Suprarenal IVC was dissected and mass was exposed. And with the use of femoral vein and right atrium, temporally veno-veno bypass was performed. Mass including IVC wall was excised and upper end of divided IVC was sutured. Lower end of divided IVC was anastomosed with 16 mm Dacron graft and graft was anastomosed with right atrium by end-to-end methods (Cavoatrial shunt). Postoperative pathologic examination revealed the mass to be organized thrombi. After 2 weeks later, follow-up IVC venography was performed and good patency was found from IVC to right atrium through artificial bypass graft and patient was discharged without complications.
CAPD용도관(用導管) 의 외과적(外科的) 삽입술(揷入術) 및 초기관리(初期管理)

A total of 548 peritoneal catheters were placed in 276 patients with end-stage renal disease during a period of 5 years between 1982 and 1987 at Soon Chun Hyang University Hospital. The actuarial catheter survival was 65% and 50% at 6 and 12 months, respectively. Of the 330 catheters removed because of various complications 156 (47%) failures occurred in the first 3 months of the CAPD with 85 (26%) failing in the first 2 weeks. In the first 2 weeks obstruction was the most frequent cause of failures (60 of 85 failures) and during the next 2 1/2 month period peritonitis (46 of 71 remov- al) was the major cause of catheter removal. Prevention of obstruction in the first 2 weeks and peritonitis thereafter are the key for better catheter survival. Surgical techniques of catheter insertion are described.

This clinical study was made of 214 cases of the jaw cysts which were diagnosed histopathologically in the Department of Oral and Maxillofacial Surgery, Wonkwang University Dental Hospital from Jan. 1, 1991 to Dec. 31, 1998. Medical records, radiographs, histopathological reports of 214 cases with jaw cysts were retrospectively reviewed. The results were as follows : 1.Among the total patient of 214 cases, male were 143 cases, and female are 71 cases, male predominated by the ratio of 2.04. 2.The periapical cysts and the dentigerous cyst are the most common cyst, irrespective of 116 cases(54.2%) and 58 cases(27.1%). 3.The periapical cyst has no gender prediction, male were 70 cases and female were 54 cases, the mean ages were 39.3 years(SD=18.4). The most common involving teeth were maxillary anterior teeth(59.7%) . 4.The dentigerous cyst predominantly occurred in third decade (18 cases : 31%), and the mean ages were 31.9 years(SD= 14.8). Dentigerous cysts predominantly occurred in male by the ratio of 7.29 (male : 51 cases, female : 7 cases). Maxillary anterior teeth(43.1%) and mandibular molars(32.8%) were most frequently involved. 5.The odontogenic keratocyst predominantly occurred in second and third decade and mean ages were 23.5 years(SD= 17.2). The mandibular molars(60%) were most frequently involved. 6.All nasopalatine cyst occurred after fourth decade, mean ages were 49.5years(SD= 10.4). In the gender incidence of nasopalatine cyst, 1 case occurred in female and 10 cases occurred in male. 7.In the surgical intervention of jaw cyst, cyst enucleation and marsupialization performed in 156 cases. Cyst enucleation with bone graft performed in 58 cases and iliac autogenous bone grafts most frequently performed in 29cases. 8.The diameter range of cyst enucleation with bone graft were from 15mm to 120mm with a cyst diameter of 33.3mm. (SD = 15.2). The diameter range of cyst enucleation and marsupialization were from 7mm to 82mm with a cyst diameter of 20.4mm.(SD=9.0) The diameter of cyst enucleation with bone graft were significantly greater than diameter of cyst enucleation. (p<0.05) 9.Post-operative complications occurred in 9 cases(15.5%) in which cyst enucleation with bone grafts performed and occurred in 31 cases(19.9% ) in which cyst enucleation.
성장호르몬이 단구 세포주 THP-1과 U937의 활성에 미치는 영향 평가

Growth hormone (GH) is a peptide hormone secreted by the pituitary gland and stimulates cell proliferation and division to promote tissue growth. In addition, the development of the immune system and the regulation of the immune response have been reported. Along with the research results related to the inflammatory control function, a correlation between the severe symptoms of COVID-19 in the elderly and a decrease in the secretion of growth hormone has recently been suggested. Therefore, this research team studied the effect of growth hormone on the proliferation and inflammatory cytokine secretion of monocyte cell lines THP-1 and U937. As a result, it was confirmed that the proliferation of THP-1 and the secretion of TNF-α and IL-1β induced by LPS were decreased by growth hormone. On the other hand, the proliferation of U937 cell line was increased by growth hormone treatment, whereas the secretion of TNF-α and IL-1β was hardly affected. In the future, the analysis of the GH receptors expressed by the two cell lines and the study of the molecular mechanism of GH action are required. In addition, it is considered that the cell stimulation technique using Poly(I:C) needs to be established more accurately.
